Examples

As shown in fig. 1 to 3, a sealed shield connector includes: plastic pipe 1, shielding net 2 and sealing ring 3.

In particular, the plastic tube 1 is made of transparent plastic to facilitate the observation of the assembly position of the internal parts.

Specifically, as shown in fig. 5, the shielding net 2 is a circular tube structure woven by intersecting metal wires, the expanded structure of the shielding net is a mesh shape, the shielding net 2 is soaked with a soldering flux to increase the weldability of the cable, the soldering flux uses rosin as a main component, and the shielding net 2 is arranged inside the plastic tube 1.

Specifically, the sealing ring 3 is made of polyolefin material, penetrates through the plastic pipe 1, is arranged at two ends of the shielding net 2 at intervals, and the melting point of the raw material of the sealing ring 3 is lower than that of the plastic pipe 1.

More specifically, before assembly, the inner diameter of the pipe 1 is larger than the outer diameters of the shielding mesh 2 and the sealing ring 3 and the plastic pipe 1.

Preferably, the length of the sealing ring 3 is greater than 2mm to ensure a sufficient sealing length and increase the sealing performance.

More specifically, the metal wire used to make the shielding mesh 2 is copper or aluminum.

Preferably, the location is such that there is sufficient contact length between the plastic tube 1 and the inner cable to increase the connection stability and tightness, the spacing between the sealing ring 3 and the shielding mesh 2 being greater than 5 mm.

Preferably, in order to prevent the sealing ring 3 from overflowing the plastic pipe 1 after being melted, the distance between the sealing ring 3 and the two ends of the plastic pipe 1 is more than 5 mm.

Preferably, the sealing ring 3 is designed blue for increased visibility and for easy visual inspection.

Preferably, as shown in fig. 4, in order to prevent the plastic pipe 1 from being punctured by the two ends of the shielding net 2 when the plastic pipe 1 shrinks, the two ends of the shielding net 2 are extruded to form smooth annular end faces, and the outer edges of the annular end faces are processed into arc structures 21 so as to form smoothness transition and avoid forming sharp edges.

The specific implementation mode is as follows: during production, as shown in fig. 1, the sealing ring 3 and the shielding net 2 are sleeved on the mandrel 4 according to the assembly requirement, wherein the assembly requirement includes the interval between the sealing ring 3 and the shielding net 2. All there is the damping force of settlement between sealing ring 3 and shielding net 2 and the dabber 4, prevents that the position of sealing ring 3 and shielding net 2 from removing in the assembling process. Then inserting the mandrel 4 provided with the sealing ring 3 and the shielding net 2 into the plastic pipe 1; heating the plastic tube 1 at a predetermined temperature and time around the plastic tube 1 to shrink the plastic tube 1, forming a structure as shown in fig. 3 after the plastic tube 1 is shrunk, fixing the sealing ring 3 and the shielding net 2 inside the plastic tube 1, and then drawing out the mandrel.

During the use, establish the connector cover at the cable junction, then the even heating connector, plastic tubing 1 will further shrink this moment to with the laminating of cable outer wall, sealing ring 3 will melt simultaneously, and fall the clearance between plastic tubing 1 and the cable and fill, form sealedly, when stopping heating, sealing ring 3 will solidify once more after the temperature reduces and form permanent encapsulated situation. The soldering flux will react with the soldering material on the cable while heating, so that a connection is formed between the cable and the shielding net 2.

The foregoing is only a preferred embodiment of the invention and is not intended to be the only or limiting embodiment of the invention. It should be understood by those skilled in the art that various changes and equivalent substitutions made herein may be made without departing from the scope of the invention as defined by the appended claims.
